@article{ISI:000251533800008, abstract = {This paper studies several issues that emerge naturally in the hydrodynamic approach to suspensions of self-driven organisms or filaments (Simha and Ramaswamy 2002 Phys. Rev. Lett. 89 058101; Kruse et al 2004 Phys. Rev. Lett. 92 078101; Hatwalne et al 2004 Phys. Rev. Lett. 92 118101). These include: a simple pictorial understanding of the instability of orientationally ordered active suspensions; the effect of translational order as well as finite geometries on these instabilities; the role of depolymerization on the possible types of alignment of active polar particles in restricted geometries; and, lastly, speculations on the relation between contractile active matter and jammed granular matter.}, article-number = {423}, author = {Ramaswamy, Sriram and Rao, Madan}, doi = {10.1088/1367-2630/9/11/423}, issn = {1367-2630}, journal = {NEW JOURNAL OF PHYSICS}, month = {NOV 30}, researcherid-numbers = {Rao, Madan/E-2927-2012}, times-cited = {40}, title = {Active-filament hydrodynamics: instabilities, boundary conditions and rheology}, unique-id = {ISI:000251533800008}, volume = {9}, year = {2007} }
